[ncl-talk] Regarding annotation

[swati shewale]

Thanks a lot Mary for quick response. I did download text file provided in
link before running annotation_5.ncl. Actually to see values of lons in
print statement, I removed minus sign from below statement that leads to
blank plot (this I rectify while comparing with your script, thanks for
your time). If text file includes all positive lons, why here used minus?
  lons       = -tofloat(str_get_field(data,3," "))

Also what 22 signifies in below statement

   city_state = str_get_cols(data,22,-1)
